A Boulder police officer accused of planning to murder his ex-girlfriend's new boyfriend resigned from the force Wednesday night just an hour before an Internal Affairs Review Panel found him guilty of breaking departmental policy, according to the Boulder Police Department.

Christian McCracken, a five-year veteran of the department, was arrested in April after police say he told his roommate -- a fellow Boulder police officer -- that he intended to kill his ex-girlfriend's new boyfriend in front of her and then kill himself. Both the ex-girlfriend and the new boyfriend are Boulder police dispatchers.

The review panel -- made up of six members of the community and six members of the police department -- unanimously agreed Wednesday that McCracken had violated a Boulder Police Department rule that requires "conformance with laws."

McCracken submitted his resignation about an hour before the panel met.

The panel's recommendation was forwarded today to Boulder police Chief Mark Beckner, who concurred with the members' decision. No disciplinary action was taken because McCracken is no longer a police officer.

McCracken has posted bond and has been released from jail. He has also left the state, which is permitted under his bond conditions, according to the Boulder Police Department.

Before resigning, McCracken had been on unpaid leave from the police department since last August, when he suffered a serious head injury while attempting to arrest a suspect outside The Sink on University Hill.
